How usual is turbo whine/whistle on a Gen 3 macan S ( or Gen 2 GTS ) ?

Recently I have noticed that its really rather loud on mine. You can’t hear it with the windows up, but with them down you can hear the turbos whine quite audibly when you blip the throttle at rest or when you pull away.

I’ve had quite a few turbo petrol cars and have never had this before. On those you could hear the wastegates open and close when applying copious quantities if loud pedal, but they never whined/whistled when blipping the throttle at idle or pulling away.

If anyone can suggest how to post video or audio clips I’ll show you what I mean.

Did they charge extra for that like they do for the noisy exhaust?

Generally means they are on their way out

Get it booked in to the dealer quick before parts blow in to the engine and destroy the whole car

I would definitely get that looked at Omni it’s not right and there is plenty of room for a catastrophic outcome here.

i’ve certainly not seen anyone say “they all do that”, so I may get the OPC to at least have a listen. 60 mile round trip is a pain though.

I could hear the turbos spool up on the Turbo while driving with windows open, say on windy roads with walls or high banks, during brief periods of acceleration. It's the same on the 911. I would never describe it as loud or intrusive, I actually quite like it. It is a known feature of turbocharged engines and is undoubtedly more noticeable on some cars more than others. But a marked increase in the sound, or a change from a smooth whine to a more 'abrasive' noise can indicate bearing failure.

The time to really worry is when you stop hearing the turbo spooling up!
